I'm having an issue of a false high fuel pressure readingon my Dynon EMS.
I came within minutes of removing the fuel pump to see if the high
pressure reg was dirty or the recirc outlet was clogged. A 5 hour job
just to uncover the pump?
I happened to be testing the installation of a replacement capacitive
fuel probe and noticed the fuel pressure was reading 10 psi and the
engine was off! I played around with re-grounding the sensor(Dynon has a
serious Achilles heal because they use ungrounded sensors) to see if
that would alleviate it but no joy.
Anybody else have this issue?
I'm thinking of switching to a GRT sensor as they are 1/2 to 1/4 the
price of Dynon's and most are grounded.
